During a field study of the forest flora carried out on Javor mountain (vicinity of the village Kladnica between Ivanjica and Sjenica) we collected a few individuals of the rare fern Oreopteris limbosperma (Bellardi ex All.) J. Holub on on the edge of the forest close to the local stream. Its last known record from Serbia supported with herbarium evidence dates back to 1875. This species was supposed to be extinct in the flora of Serbia and this is its first confirmed record after almost 140 years. © 2015 Institute of Botany and Botanical Garden Jevremovac, Belgrade.

Road construction and usage have a wide range of direct and indirect negative effects on protected areas. The impact of state roads on protected areas in Vojvodina was reviewed in this article, based on the orientation values of habitat loss and secondary negative effects originating from traffic functioning. Results of the assessment indicate that the use of existing roads constructed on habitats within the national ecological network exceeded the capacity of individual PA-protected areas (e.g., in case of Straža Natural Monument). Recorded capacity overflow on other PAs occurs solely as a consequence of overlapping between protected areas and areas of influence of roads routed along the borders of protected areas (which is the case with Slano Kopovo Special Nature Reserve and Selevenjske pustare Special Nature Reserve). The aim of this article is to show that even with the smallest values of the parameters related to the width of roads and critical distance from the habitat, the vulnerability of certain core areas of the national ecological network is evident.

During field studies of semi-saline meadows and marshes carried out along the Ponjavica River in the vicinity of Banatski Brestovac (Vojvodina, Serbia), we found several specimens of Sporobolus indicus (L.) R. Br. The plant grows in transitional zones between disturbed damp mesotrophic grassland vegetation and semiaquatic communities belonging to the alliance Bolboschoenion maritimi continentale Soó. This adventive and potentially invasive species with a worldwide distribution has never before been recorded in Serbia.

Elatine hungarica Moesz is a small wetland ephemerophyte that occurs and is classified as extinct, data deficient or a very rare and endangered taxon in most countries in eastern and central Europe. Based on literature and herbarium data, supplemented by 160 field records collected between 1998 and 2011, we present the currently known distribution of this species in the Pannonian Basin, which mostly but not exclusively includes Hungary. Within the Pannonian Basin this species is distributed throughout Hungary, with sporadic occurrences in Romania, Serbia and Slovakia. The temporal distribution of floristic records is very uneven. This species was recorded only in 27 years during the last 213 years (1798-2011). When examining presence/absence data for most of the 20th century, we found a significant correlation between the number of records of this species in a given year and two key, but not independent, environmental variables: rainfall and the extent of the area inundated in the same year. In the more intensively documented period between 1998 and 2010, there is only a significant correlation between the numbers of records of this species and the extent of flooding, which is because there is a delay in the effect of an increase in rainfall. The peak occurrence of records in the 1940s and 1950s is associated with extensive rice production in Hungary. Today, most records are for agricultural fields that are subject to flooding and becoming temporary wetlands. The comparison of recent and past distributions of E. hungarica reveals a consistent and marked regional difference; whereas this species is not rare along the Tisza river and its tributaries, it is markedly scattered in similar habitats near the Danube.

Microbial Drug Resistance | Year: 2012

This study concerned the occurrence of fecal bacteria with plasmid-mediated quinolone resistance (PMQR) genes in rooks (Corvus frugilegus, medium-sized corvid birds) wintering in continental Europe during winter 2010/2011. Samples of fresh rook feces were taken by cotton swabs at nine roosting places in eight European countries. Samples were transported to one laboratory and placed in buffered peptone water (BPW). The samples from BPW were enriched and subcultivated onto MacConkey agar (MCA) supplemented with ciprofloxacin (0.06mg/L) to isolate fluoroquinolone-resistant bacteria. DNA was isolated from smears of bacterial colonies growing on MCA and tested by PCR for PMQR genes aac(6′)-Ib, qepA, qnrA, qnrB, qnrC, qnrD, qnrS, and oqxAB. All the PCR products were further analyzed by sequencing. Ciprofloxacin-resistant bacteria were isolated from 37% (392 positive/1,073 examined) of samples. Frequencies of samples with ciprofloxacin-resistant isolates ranged significantly from 3% to 92% in different countries. The qnrS1 gene was found in 154 samples and qnrS2 in 2 samples. The gene aac(6′)-Ib-cr was found in 16 samples. Thirteen samples were positive for qnrB genes in variants qnrB6 (one sample), qnrB18 (one), qnrB19 (one), qnrB29 (one), and qnrB49 (new variant) (one). Both the qnrD and oqxAB genes were detected in six samples. The genes qnrA, qnrC, and qepA were not found. Wintering omnivorous rooks in Europe were commonly colonized by bacteria supposedly Enterobacteriaceae with PMQR genes. Rooks may disseminate these epidemiologically important bacteria over long distances and pose a risk for environmental contamination. © 2012 Mary Ann Liebert, Inc.

Salt steppes and marshes represent the most valuable ecosystems in the world, providing numerous ecosystem services that are extremely vulnerable to anthropogenic influences. These types of habitat in the territory of Serbia are most dominant in Banat and a significant portion of them is under protection or in the process of becoming protected. The section surrounding the protected areas of Slano Kopovo Special Nature Reserve, Rusanda Nature Park and Okanj Bara Special Nature Reserve with the non-building area of Novi Bečej, Kumane, Melenci, Elemir and Taraš cadastral municipalities, has been chosen for the analysis. The aim of this paper was to assess the influence of specific anthropogenic factors on the elements of an ecological network using the analytical method that can generate the required results in a manner suitable for presentation to various stakeholders. To achieve this aim, the Leopold matrix model, used for assessing anthropogenic influence on the environment, has been chosen. The specificity of this issue of protecting and preserving elements of an ecological network resulted in the need to isolate and evaluate the factors affecting the preservation of habitats and functionality of ecosystems, unlike the concept of Leopold matrix, which treats all factors as equally important in the process of evaluation. Evaluation results indicate significant effects of historical, perennial manner of using the area and other resources in the non-building area.

More than 75% of Vojvodina province (Serbia) are agricultural and mostly degraded landscape intermingled with more or less isolated remnants of natural and seminatural vegetation on areas which are unfavourable for amelioration into arable land (steep loess walls, sandy areas, saline marshes and meadows) or they are included within protected areas. Many of them were proved to be important centers of floristic and ecosystem diversity in Serbia and Pannonic region, especially for steppe and halophytic vegetation. Unfortunately, significant part of this valuable sites are unprotected and under great antropogenic influences which emphasize need for their protection. One of these important sites is saline lake Okanj bara near Tisa river in Vojvodina (Serbia) with specific and endangered types of saline habitats. Based on field research, herbarium and literature survey new floristical and ecological data are presented. In accordance with data from related literature more than 400 taxa and 58 syntaxonomical units (7 classes, 12 orders, 16 alliances, 20 associations) were observed. In group of protected and rare typical species as well as species with insufficiently known distribution in Serbia were recorded: Plantago schwarzenbergiana Schur, Aster tripolium L. subsp. pannonicum (Jacq.) Soó, Cirsium brachycephalum Juratzka, Trifolium angulatum Waldst. & Kit., Allium atropurpureum Waldst. & Kit., Scilla autumnalis L., Silene viscosa (L.) Pers., Salvia austriaca Jacq., Salsola soda L., Scirpus lacustris L. subsp. tabernaemontani (C. C. Gmelin) Syme in Sowerby, Crypsis aculeata (L.) Aiton, Artemisia santonicum L., Limonium gmelinii (Willd.) O. Kuntze and others. © 2011 Vasile Goldis University Press.

Park in Novi Knezevac was established in the nineteenth century, and it surrounds the manor of Marko Djurkovic - Servijski. During the nineteenth century and early twentieth century further developing of the garden was associated with construction of the manors of Tallián, Feilitzsch and Maldeghem families. Whole park together with the manors of former aristocratic families, two of which have the status of cultural monument, makes unique ambient. Park is located in the old nucleus of Novi Knezevac. West side of park reaches the Tisa river. In this paper landscape-architectural, dendrological, cultural, historical and other values of Park in Novi Knezevac - protected natural monument of garden architecture were analyzed. Analysis of dendroflora was carried out in 2008. As a result 1137 woody plants (238 coniferous and 899 deciduous) within 56 species and lower taxa was recorded. Dendrological parameters of 38 representative trees were measured as well as their decorative features and vitality. The aforementioned parameters are given in table. Based on the analysis of the current state of the park, values, historical genesis and current needs, measures of the protection and promotion, preservation and renewal of the park were proposed. © 2012 Vasile Goldis University Press.
